The Packet Sniffer is a tool for capturing IEEE 802.15.4 traffic. Using Wireshark, it can decode and analyze Thread, KNX-IoT and Zigbee packet headers.
The Packet Sniffer dongle is available from our distributors. It consists of a Chili2D module pre-programmed with dedicated packet sniffing firmware.
Get the Cascoda Windows Tools installer from our Releases page, and install it so that you have access to the sniffer executable.
Install Wireshark from the official website, if it is not installed already.
Plug in your Packet Sniffer dongle, and run the sniffer executable. To start a live capture on channel 15, you must open the Command Prompt and type sniffer -w 15.
In order to decrypt Thread frames successfully, you will have to inform Wireshark of the Thread network decryption key. If you have the KNX-IoT access tokens, OSCORE security can also be decrypted here. See our sniffer documentation for detailed instructions.
